Research on Load-Following Characteristics of Pressurized Water Reactor Nuclear Power Plants

Pressurized Water Reactor（PWR） Nuclear Power Plants（NPPs） realize the load following through the Power Control System（PCS）.In this paper,the fuzzy controller was introduced into PCS to make the optimal rod control and boron concentration adjustment.A power compensation channel was proposed to accelerate the response speed.The simulation results in Matlab illustrated the excellent load-following capability of NPP with PCS.Through the user-defined program of PSASP,PCS module was embedded with the whole NPP model.The simulation results in PSASP showed that the load-following capability of NPP meets the industrial technical requirements,and demonstrated the capability of NPP for power system daily peak load regulation.
